Wifi missing on ACER Aspire one netbook 751h

Post by nano »

Hi everibody,
I've got a netbook Acer Aspire ONE model 751h (alias model ZA3) with 2GB ram and 240 GB SSD.
Wifi under Windows 7 Starter and Linux Mint LDME5 32bit is working out of the box: I can activate/deactivate wifi chip through a small switch in front of the netbook.
BUT...
Windows 7 is TOO obsolete and unsecure while Mint LDME5 is TOO heavy for this hw.
So I decided to give Salix 15 32bit a try...
Installation went smooth (I'm used to Slackware) but even if wifi hw is "seen" by the OS it seems it remains OFF whenever switch position. Network Manager do not show any WIFI only wired.
Here under the info I've obtained from the OS:

Last entry shows that hw is recognised,
Then I checked if it is "blocked":

Code: Select all

sudo rfkill
Password: 
ID TYPE      DEVICE              SOFT      HARD
 0 wlan      acer-wireless    blocked unblocked
 1 bluetooth acer-bluetooth   blocked unblocked
 2 wwan      acer-threeg    unblocked unblocked
 4 wwan      hso-0          unblocked unblocked
So I tried to activate it with

Code: Select all

sudo rfkill unblock wlan
sudo rfkill
ID TYPE      DEVICE              SOFT      HARD
 0 wlan      acer-wireless  unblocked unblocked
 1 bluetooth acer-bluetooth   blocked unblocked
 2 wwan      acer-threeg    unblocked unblocked
 4 wwan      hso-0          unblocked unblocked
At this point hw is ok and unblocked but... but still no entry under network manager , only wired connections.

Any suggestions?
Thank in advance

You have a broadcom card. We can't legally distribute firmware for that. You'll need to build and install b43-fwcutter and b43-firmware packages with slapt-src. Of course you'll need to connect through ethernet to do that.

Code: Select all

sudo slapt-src -u
sudo slapt-src -i b43-firmware
reboot and it should work.

Thank Gapan for your replay,

I connected to internet by wire and followed your instruction:

First I update the system
sudo slapt-src -u

then I installed firmware cutter with
sudo slapt-src -i b43-fwcutter

everything went smooth

but when I launch
sudo slapt-get -i b43-firmware
it exit with "Packet not found: b43-firmware"
Am I missing something?

You should use slapt-src to build and install b43-firmware, not slapt-get. That was my mistake, I'm sorry.
